Tobias,
A few years ago we were approached by Froglogic about working out an adapter for Squish, but nothing ever ended up coming of it from our end. There are a couple things I would recommend doing.
1. Contact Froglogic. They might have ended up putting something together that we don't know about.
2. Open a case with support and request Squish support. We can enter an enhancement request and forward it on to our development team.
If those don't work out, we can contact our Services team to see about building the adapter for you.
